I found lots of interesting information in this forum. I sincerely thank all participants for their assistance to the community.
We have a problem for which I did not find all the necessary information.
We need to integrate an existing volume in a dataset.
The volume has been created manually before storage system integration in OCUM.
This volume contains about 180 qtrees with quota.
We created a dataset with adequate provisioning policy.
We added the volume to the dataset.
We increased the number of qtree volume in general options "dfm options set maxQtreesPerVolume = 200" and in options of the dataset "dfpm dataset set <dataset> maxQtreesPerVolume = 300".
Despite these options, OCUM creates a new volume when we ask for provisioning a new space.
We want to continue to create new spaces (qtrees) in the existing volume.
How is it possible to force OCUM to use the existing volume instead of creating a new one ?
Many thanks for your help.
